GOLF-BALL.

SPECIFICATION forming-,part of Letters Patent No. 701,738, dated J une 3, 1902.

Application filed April 23, 1902. Serial No. 164.316. (No model) T0 all whom t 11i/wy concern:

Be it known that I, ELEAZER KEMPSHALL, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Golf-Balls, of which the following is a specification.

This invention relates to playing-balls, es-v pecially to those used in the game of golf ;l and its object is to provide a ball having great strength, durability, and driving power Without being unduly sensitive to a light blow.

The part-sectional drawing forming apart of this specification illustrates a ball made according to my present improvements.

For the filling of the ball I prefer to use a soft-rubber sphere l, which may have a hard center piece 2, preferably of gatta-perche.. Upon the rubber sphere I compress hemispherical segments of celluloid or its equivalent, thus forming a shell 3, the weld of said Segments being indicated at A. This shell is preferably lined with fabric 4, which is incorporafed with the'celluloid and preferably cemented upon the rubber. Upon the celluloid shell I apply a casing 5 of gutta-percha, preferably in the form of heinispherical segments, the weld thereof, as indicated at B, running crosswise of the weld A, so that each of said casing and shell elements may reinforce the weld of the other thereof. The gutta-percha casing I preferably line with fabric 6, although this layer of fabric may beincorporated in the celluloid sphere before the gutta-percha casing is applied. Preferably the compound shell of celluloid and guttapercha holds the soft-rubber sphere 1 under compression.

By the described construction I impart to the ball a high degree of liveliness, this being due to the presence of the celluloid shell, which is relatively thin, and instantly recovers its shape when the ball is distorted by a blow, so that the ball flies with great energy. By having a casing of gutta-percha on said celluloid shell the latter is prevented from being ,dented sharply and cracked by a golf-club, while the gutta-percha itself in no small degree contributes to the flying quality of the ball. By having a backing of soft rubber the sprngy qualities of the celluloid shell iare developed, while the gutta-percha center piece 2 cooperates with the rubber sphere and with the .remainder of the ball in absorbing power from the club and contributing to the flying ability of the ball. The fabric not only secures a close union between the celluloid and the inner and outer layers of rubber and gutta-percha, but also yimparts to the ball the quality of being dead when given a light tap by an implement, thus adapting the ball forfputting.

It is not essential in all cases that fabric be employed in"`connection with the rubber 'shell or layer 3.

Having described my invention, I claim-'- 1.- A playing-ball comprising a sphere of soft rubber, a shell of celluloid thereon, and a shell of gatta-percha upon said celluloid.

2. A playing-ball comprising a sphere of soft rubber, a shell of celluloid thereon, and a shell of gutta-percha upon said celluloid; said celluloid and gutta-percha shells holding said soft rubber under compression.
